Frank,
Please do the following and report to us what you get.
Open a python session and write
from cdma import cdma_parameters as cp
What is the result of this?

Frank,
you have to follow the procedure in README by compiling ONE file at a
time,
and RELOADING the blocks as you go on, ie,
Load the hier block “amp_var_est_hier.grc”,
Compile it (this little button on GRC that looks like a pyramid, a
sphere
and an arrow)
Reload it (this little circle button on GRC)
Load “cdma_tx_hier.grc”,
compile it as before
reload
Load “chopper_correlator.grc”,
compile
reload
etc…
“cdma_rx_hier.grc”, “cdma_tx_hier1.grc”, “cdma_rx_hier1.grc” and
compile
them

OK, great.
This is due to the fact a recent pull request has not yet been merged
into
gnuradio.
SO the constellation module does not have yet the
“constellation_8psk_natural”
constellation.
There is a simple fix to that:
please go to your gr-cdma/python directory
and edit the file
cdma_parameters.py
In particular in line 124 change “digital.constellation_8psk_natural”
with
“digital.constellation_8psk”.
Now you have to make, sudo make install, sudo ldconfig one more time.
Once you do that, please open a python session and redo
from cdma import cdma_parameters as cp
and let us know what you get.
(if you don’t get any errors you are ready to go!)

Frank,
please pull the latest version of gr-cdma.
You have to make a small edit in the cdma_parameters.py file
(see updated README file) before you install it.
Once you do that, open a python session and do
from cdma import cdma_parameters
This should now give no errors.
Let us know of your progress.
Achilleas
Hi Frank,
For the same reason, constellation_16qam is not in the current
constellation module yet. Unlike 8psk_natural which you have a
replacement
constellation_8psk, no 16-ary constellation is available in current
constellation module.
You can try to modify the cdma_parameter.py by deleting the tcm type
16qam+rate 2/4 convolutional code.
Just delete digital.constellation_16qam() in payload_mod, pdir+
awgn2o4_8_ungerboeckc.fsm in fsm, and trellis.fsm(4,4, blabla…) in
uncoded_fsm.
If I missed anything, please be careful to delete anything related to
16qam
and 2/4 cc code. It would be easy.
You should be able to run it with two tcm types.
Best,
Zhe
yes, please disregard all previous changes.
They have been incorporated in the updated files.
So, please pull a clean copy from github.
Achilleas
Hello Achilleas, thank you I will do that! When I perform this edit in
the python file should I disregard the changes we did yesterday in th
cdma_parameters.py file line 124 which was changing the
“digital_constellation_8psk_natural” with “digital.constellation_8psk”
and keep the orginal code?

All the blocks were able to load, compile and show on the GRC blocks
list except from the “cdma_tx_hier1” and “cdma_rx_hier1” block (they are
producing errors and are few of their blocks are marked red because of
this). Then the “cdma_txrx1” block is producing a error because it needs
the “cdma_tx_hier1” and “cdma_rx_hier1” block in order to compile.

You shouldn’t worry about these files for now.
In any case they refer to “adaptive modulation”
which you cannot do unless some recent updates are merged into gnuradio
master.
For now, you should be able to experiment with the txrx, tx, rx.

This is the result after making the prefix modification in the
cdma_parameters.py file and opening a python session:
from cdma import cdma_parametersCDMA PARAMETERS : for adaptive modulation
bits_per_header= 36
symbols_per_header= 36
bits_per_coded_symbol = [2, 3] for [uncoded QPSK, rate 2/3 cc &8PSK]
respectively.
payload_bytes_per_frame= 50
symbols_per_frame= 260
trellis_coded_payload_symbols_per_frame= 216 for [uncoded QPSK, rate
2/3 cc &8PSK] respectively.

respectively.
additional_bytes_per_frame= [1, 1] for [uncoded QPSK, rate 2/3 cc

you have wasted [0.01818181818181818, 0.012195121951219513] percent of

You have to make a small edit in the cdma_parameters.py file
(see updated README file) before you install it.
Once you do that, open a python session and do
from cdma import cdma_parameters
This should now give no errors.
Let us know of your progress.

This is due to the fact a recent pull request has not yet been merged

SO the constellation module does not have yet the
“constellation_8psk_natural”
constellation.
There is a simple fix to that:
please go to your gr-cdma/python directory
and edit the file
cdma_parameters.py
In particular in line 124 change “digital.constellation_8psk_natural”
with “digital.constellation_8psk”.
Now you have to make, sudo make install, sudo ldconfig one more time.
Once you do that, please open a python session and redo

Hello. So the “cdma_tx” file compiles and runs via using the USRP as the
sink. However on my other laptop with the USRP connected, the “cdma_rx”
file excutes and produces this error:
Using Volk machine: avx_32_mmx_orc
terminate called after throwing an instance of
'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injectorboost::thread_resource_error
’
what(): boost::thread_resource_error
By the way I am atempting to do live cdma transmission using the USRP’s
and disabling the cdma.fifo file sink and file source since this doesnt
apply to me.

no hardware attached, while the cdma_tx.grc and cdma_rx.grc are used for

It should be obvious that this can be done.
A transmitted signal over the air can be received from multiple
receivers…
Indeed, the cdma_txrx is a simulation of the entire tx/rx.
We used it to test our system and everyone can use it if they
don’t want to (or cannot) transmit through real hardware.
The separate files cdma_tx and cdma_rx can be used with
real USRPs.

blocks and can therefore not compile. The error states "name ‘cp’ is not defined.
And the import box is showing this error “Bad import syntax:import
cdma.cdma_parameters as cp”. This is where I am stuck at because it seems all the
other blocks that are producing errors has this ‘cp’ in it somehow.

you have to follow the procedure in README by compiling ONE file at a
time,
and RELOADING the blocks as you go on, ie,
Load the hier block “amp_var_est_hier.grc”,
Compile it (this little button on GRC that looks like a pyramid, a
sphere and an arrow)
Reload it (this little circle button on GRC)
Load “cdma_tx_hier.grc”,
compile it as before
reload
Load “chopper_correlator.grc”,
compile
reload
etc…
“cdma_rx_hier.grc”, “cdma_tx_hier1.grc”, “cdma_rx_hier1.grc” and
compile them

| Hello Sir, I have read the readme.md file already. My first issue is where it
states to “load all the hier blocks and compile them”. When I loaded them via the
GRC by clicking on “open an existing flowgraph” and selecting the files, I see
that they all are missing some variables, information, and even blocks, and are
shown as red.
I have taken a picture to show you this. I am using version 3.7.5.1 of
GNuRadio by the way

There is no such instruction to be executed!
Please read the README.md file and let us know which one of the detailed
instructions mentioned there you don’t know how to execute.

Ok. First instruction that I do not know how to execute is the import
variable block that says “import coma.cdma_parameters as cp”. What
exactly am I supposed to be replacing in this section.

Hello, What type of code sequences are you using for this CDMA module.
(Maximum Length Sequences, Walsh Hadamard, Gold codes, etc). I see
something here called Kronecker filter but am not too sure what that
is.
